Dry tap and spinal anesthesia

Spinal anesthesia in a caesarian case after dry tap

“…[2] Although there are many causes explained for dry tap as mentioned before, but after ruling out absence of all cause, still there was a dry tap. This case also can put front another wide scope of research on causes of “dry tap.”…”

“…The query may arise for multiple attempts, but in this case the patient was not willing with general anesthesia and even if newer techniques have evolved like epidural stimulation,[3] but multiple attempts for spinal anesthesia still holds first-rate. [2] Again, a case was reported that dry tap lead to epidural abscess, but this case went uneventfully, where may be the patient's general condition and associated infection at a different site may also take a concern regarding any post-operative infections. However, this case was young and fit without any associated illnesses.…”

“…It is possible that in patients with “absent” CSF or very low CSF pressure, the subarachnoid space is obliterated as the arachnoid “collapses” on the pia. [2] this increases the volume of the subdural space and may explain the absence of CSF. However, in this case, needle change was tried, tried with proper spaced identified, hydration was also proper; almost two ringers lactate was transfused when she was put to an operation table.…”

“…A major advantage of spinal anesthesia is its definitive endpoint, i.e., the free flow of CSF. [1] However, if it happens that no CSF comes even if being in the proper space then it is said to be a condition known as “dry tap.”[2] Although it's a rare incidence, but a very troublesome condition during a subarachnoid block (SAB). Even, if cases have been published regarding dry tap, but successful block without complication is rare among rarest cases.…”

Failure after cerebrospinal fluid flow and success after no cerebrospinal fluid flow during spinal anesthesia induction for intrapartum cesarean section -A report of two cases-

“…Causes of this rare phenomenon, also called "dry tap," include a blocked needle, history of spinal surgery, spinal stenosis, adhesive arachnoiditis, and low CSF pressure [6,7]. The patient experiencing this dry tap phenomenon had no history of spinal surgery, symptoms of spinal stenosis, or adhesive arachnoiditis.…”
